Diodes - Zener - Arrays

The BZB84-C2V7,215 is part of the Diode – Zener Diode – Array range of semiconductor devices. It is a 5-pin, array package device that contains three Zener diodes and two integrated antiparallel Zener diodes. The device is capable of handling high frequency current, making it an ideal choice for the protection of circuit components from over-voltage and reverse current. Equally, it can provide regulated DC voltage.

Application Fields

The broad range of application fields for the BZB84-C2V7,215 include:

• Switch Mode Power Supply (SMPS): The SMPS are highly efficient, AC/DC or DC/DC switching power systems, using pulse width modulation (PWM) or pulse frequency modulation (PFM). The Zener diode array contained within the BZB84-C2V7,215 is ideal for the protection of the power electronics from over-voltage.
• Switching Regulators: As well as being used for power regulation, the BZB84-C2V7,215 can provide highly regulated voltage outputs in switching regulators. The output of the regulator is highly dependent on the Zener diodes contained within the package.
• Automotive Applications: Automotive applications, such as voltage regulators, relays and switches, often need reverse polarity protection and low voltage dropouts. The Zener diode array contained in the BZB84-C2V7,215 provides the ideal solution for these applications.

Working Principle

As previously mentioned, the BZB84-C2V7,215 is a 5-pin array package device that comprises of three Zener diodes and two integrated antiparallel Zener diodes. The Zener diodes are PN-junction diodes, with a Zener breakdown voltage of 215V. The integrated antiparallel Zener diodes have a breakdown voltage of 15V. All of the diodes are connected in anti-parallel fashion, meaning that the sum of the voltages must be zero. When subjected to an overload voltage, the Zener diode will conduct current from anode to the cathode and thereby protect its component from the over-voltage.

In its application as a voltage regulator, the BZB84-C2V7,215 is placed in series with the DC power supply. When the voltage drops below its desired level, the Zener diode will start to conduct current, thereby providing a steady regulated voltage supply.

Conclusion

The BZB84-C2V7,215 is an ideal choice for applications requiring reverse polarity protection and low voltage dropouts. It is capable of handling high frequency current and can provide a highly regulated DC voltage output. The three Zener diodes and two integrated antiparallel Zener diodes contained in the package make it a versatile solution for a wide range of applications.
